General Rules

Before making any connections to the MODEM, note the following rules:

zEthernet Port (RJ-45)

All network connections to the Modem Ethernet port must be made using Category

5 UTP for 100Mbps; Category 3,4 UTP for 10Mbps No more than 100 meters of cabling may be use between the MUX or HUB and an end node.

zPhone Port (RJ-11)

All Phone set connections to the RJ-11 Port made using 24~26 Gauge phone wiring.

Connecting the MODEM

The Modem has one Ethernet port which support connection to Ethernet operation. The devices attached to these ports must support auto-negotiation or 10Base-T OR 100Base-TX unless they will always operate at half duplex.

Use any of the Ethernet ports to connect to devices such as NIC, Switch, bridge or router. You can also connect to another compatible Modem to an RJ-45 port on the other device.

The RJ11 Line port is used to connect to the wall RJ-11 modular socket (outlet) which is connect to VDSL 4-Band CPE Modem side (Point to point solution)

The RJ11 Phone port of the Modem can connected to a telephone and a computer sharing one telephone wire for making calls and accessing the internet at the same time.

Connecting the RJ-11/RJ-45 Ports

1. The Modem’s RJ-11 ports supports max distance 1.9Km at 5M/5M or max speed 25M/25M symmetrical and distances up to 800m data service across existing phone wiring, without interfering with standard voice transmissions, easy-to-use does not require the installation of any additional wiring. Every RJ-11 modular phone jack in the home can become a port on the LAN. Networking devices can be installed on a single telephone wire that can span within 1.9Km or 800m (depend on speed) between the two farthest points. (Figure 1.0).

2. VDTU-101/201 Modem has embedded Splitter between every VDSL side (Line) and POTS (Phone) side. It permit you to deliver broadband service on the same lines as Plain Old Telephone Service (POTS), PBX, ISDN traffic and VDSL Signal.

Appendix C: Troubleshooting

Diagnosing the Modem’s Indicators

The Modem can be easily monitored through its comprehensive panel indicators. These indicators assist the network manager in identifying problems the hub may encounter. This section describes common problems you may encounter and possible solutions

1. Symptom: Power indicator does not light up (green) after power on. Cause: Defective External power supply

Solution: Check the power plug by plugging in another that is functioning properly. Check the power cord with another device. If these measures fail to resolve the problem, have the unit power supply replaced by a qualified distributor.

2. Symptom: Link indicator does not light up (green) after making a connection.

Cause: Network interface (e.g, a network adapter card on the attached device), network cable, or switch port is defective. Solution: Power off and re- power on the VDSL Modem.

Verify that the switch and attached device are powered on. Be sure the cable is plugged into both the switch and corresponding device. Verify that the proper cable type is used and its length does not exceed specified limits. Check the Modem on the attached device and cable connections for possible defects. Make sure phone wire must be connected between VDTU-101 and VDTU-201 first, when both are be power on. Replace the defective Modem or cable if necessary.

3. Symptom: VDSL Link cannot be established Cause: VDSL auto speed failure, or phone cable length is over specification with

the limit of 1.9km or not a 24 gauge phone wire with twist pair.

Solution:

3.1 Please make sure phone wire must be connected between VDTU-101 and VDTU-201 when both are power on. VDTU-101 will do auto speed function depending on phone wire length, therefore if VDTU-101 can’t detect VDTU-201 over phone wire while both power on, this will cause the link to fail.

3.2 Please check phone cable must be 24 gauge with twist pair and without rust, and the length is not over 1.9km.

Note : Phone cable must meet Cat. 3 standard or above and without clustering,

otherwise will cause more cross talk issue to reduce VDSL power driver.

Page 15

VDSL 4-band Modem Manual

CTC Union Technologies Co., Ltd

4. Symptom: VDSL always Link on 5M/5M speed mode at short phone cable. Cause: VDSL auto speed stop. Solution: Please re-plug in phone cable between VDTU-101 and VDTU-201, or

re-power on VDTU-101 and VDTU-201 again.

Note : VDTU-101 will do auto speed function while phone cable re-plug in or

re-power on.

5. Symptom: We tested with a regular S0 bus from an NTBA - data works, but ISDN telephone does not.

Solution: You must connect according to the following chart if you want to connect

CO and CPE with NTBA.

Power and Cooling Problems

If the POWER indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or internal power supply as explained in the previous section. However, if the unit power is off after running for a while, check for loose power connections, power losses or surges at the power outlet, and verify that the fan on back of the unit is unobstructed and running prior to shutdown. If you still cannot isolate the problem, then the internal power supply may be defective. In this case, contact your dealer.

Installation

Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (e.g., the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly.

Page 16

VDSL 4-band Modem Manual

CTC Union Technologies Co., Ltd

Transmission Mode

The default method of selecting the transmission mode for RJ-45 ports is 10/100 Mbps ETHERNET, for RJ-11 port are 5/15/25Mbps VDSL. Therefore, if the Link signal is disrupted (e.g., by unplugging the network cable and plugging it back in again, or by resetting the power), the port will try to reestablish communications with the attached device via auto-negotiation. If auto-negotiation fails, then communications are set to half duplex by default. Based on this type of industry-standard connection policy, if you are using a full-duplex device that does not support auto-negotiation, communications can be easily lost (i.e., reset to the wrong mode) whenever the attached device is reset or experiences a power fluctuation. The best way to resolve this problem is to upgrade these devices to a version that support Ethernet and VDSL.

Physical Configuration

If problems occur after altering the network configuration, restore the original connections, and try to track the problem down by implementing the new changes, one step at a time. Ensure that cable distances and other physical aspects of the installation do not exceed recommendations

System Integrity

As a last resort verify the switch integrity with a power-on reset. Turn the power to the switch off and then on several times. If the problem still persists and you have completed all the preceding diagnoses, then contact your dealer
